Subject: [PATCH] imsm: allow to specify second volume size
Git-commit: 1a1ced1e2e64a6b4b349a3fb559f6b39e4cf7103
Patch-mainline: mdadm-4.1+
References: jsc#SLE-10078, jsc#SLE-9348

Removed checks which limited second volume size only to max value (the
largest size that fits on all current drives). It is now permitted
to create second volume with size lower then maximum possible.
